cannot even ping plz help

[Guest]

I have a simple home networking between two computers, A and B. I connect to
the Internet through A and also have a printer connected to it. From B I used
to be able to acces the Internet and print through the Ethernet connections
through a simple Ethernet Switch.

Recently I bought Norton Anti-Virus 2007 and installed it first on A and
later to be on B as well. However trouble immediately surfaced after I
installed it on A. I suddenly lost all communications between the two
computers. I have tried just about everything I could think of:

1) Un-installed and wiped out all trace of Norton from A.
2) System restored A.
3) Disabled anti-virus on B.
4) Re-run Network Setup Wizard on both computers with A as main Internet
access and B going through A for access.
5) Made sure Win XP firewall was NOT en-abled on both computers.
6) Made sure File Sharing and Printer Sharing are enabled on both computers.

Nothing worked. Now when I ping A from B or B from A using IP addresses all
I got is an error message "Destination host unreachable".

I have repeated the above steps ad-nauseam and am now desperately stuck.
Please help.

Darren,

Did you solve this problem? I am currently experiencing a very similar
issue. We have a small workgroup, 3 xp home computers and 1 xp pro, also a
2003 workgroup server. the xp pro computer and only ping a couple of the
computers on the network. Incidentally, the xp pro box had norton AV
running. We uninstalled it, but still can't ping. We've tried all the steps
you've listed below plus enabling netbios over tcp/ip. Please let me know if
you solve this problem.

thanks,
Mike
